You know that moment. Flu season hits, someone at work is coughing, and you wonder: how bad is it actually right now? InfectRisk gives you a clear answer. No complicated reports, no 50-page PDFs. Just a simple risk score for your area, updated daily. We pull from three sources most people never see: official case data from health authorities like the CDC and ECDC, wastewater surveillance (the earliest signal for new waves), and dark figure estimates. Because official numbers only tell part of the story. The app learns about you too. Your age, health, location. These change what "risky" actually means. A 65-year-old visiting grandkids during peak flu season needs different information than a healthy 25-year-old. You get yours. A few things we're proud of: - Data from 32 countries across Europe and North America - A Home Screen widget so you never have to open the app - Actionable tips, not just numbers - Buy once, use forever — no subscriptions, no hidden costs - 8 languages, no ads, no sign-up Built for anyone who'd rather check the data than guess. Especially if you're over 60, caring for someone vulnerable, raising little ones who bring home every bug from daycare — or simply looking after your health. InfectRisk doesn't replace your doctor. It helps you ask better questions. And get sick less often. Questions? hey@infectrisk.com Website: https://www.infectrisk.com Privacy policy: https://www.infectrisk.com/en/datenschutz
